The receiving tank 5 is correspondingly disposed in the machine stand 1to receive and load up the heated and cooked foodstuffs which are dumpedout from the stir-frying rotary tank 22. The receiving tank 5 iscontrolled by an automatic push rod 52 to move forward and backward.That is, the receiving tank 5 is capable of being drawn out from andstored in the machine stand 1 automatically by the automatic push rod52. In correspondence to the receiving tank 5, a sensor 51 is disposedon the machine stand 1 to correspondingly detect and monitor themovements of the receiving tank 5.

The cleaning unit 6, which includes a water hose 61 and an air hose 62,is disposed at where is corresponding to the stir-frying rotary tank 22on the machine stand 1, so as to clean the stir-frying rotary tank 22 bywatering and blowing.

The drying unit 7 includes a funnel-shape tank 73 used for directing thewasted water to flow into the leftovers collecting tank.

The drying unit 7 further includes a set of slide tracks 71 disposedbelow the receiving tank 5 under the machine stand 1.

The drying unit 7 further includes a drawer recycling tank 72 capable ofsliding on the slide tracks 71 for being drew out from or pushed backinto the machine stand 1. The drawer recycling tank 72 has a bottom sidewhich is opened with multiple apertures 721. A funnel-shape tank 73 isdisposed under the drawer recycling tank 72 on the machine stand 1 inorder to drain out the wasted water.

The control unit 8 which is correspondingly disposed on the machinestand 1 has a control panel 81 and a temperature transceiver 82 fordetecting the temperature for the heated stir-frying rotary tank 22. Thecontrol unit 8 is used for controlling the action period of theautomatic stir-fryer and the temperature of the strove unit 3.

Please refer to FIG. 1 to FIG. 9. The automatic stir-fryer is applicableto stir-fry massive foodstuffs or food ingredients or to heat up thehalf-baked foodstuffs, the medium-rare foodstuffs, the instant foods orthe ready-cooked products.

Prior to using, multiple sets of electromagnetic valves 302 are disposedon the main rack 301 of the thermal power adjusting unit 30. There aretotally four sets of electromagnetic valves 302 shown in FIGS. The wayto adjust the four sets is mainly to revolve the tuning knobs 303disposed on the respective electromagnetic valves 302 on the main rack301, so as to adjust the gaseous discharges respectively andcorrespondingly (the thermal power source is preferably selected from agroup consisting of a natural gas, a liquefied natural gas and aliquefied petroleum gas, which is not shown in Figs.). In thisembodiment, there are four different thermal power stages including afully-opened discharge stage, a large-flame discharge stage, amiddle-flame discharge stage and a small-flame discharge stage providedfor the respective valves. As if the foodstuffs to be cooked demand moreaccurate and multi-level variety for the cooking temperature, thenumbers of the sets of the electromagnetic valves 302 can be increased.The numbers of the sets of the electromagnetic valves 302 can be variedupon the actual demanding. After then, the thermal power adjusting unit30 is connected with the control unit 8 on the automatic stir-fryer.

While using, the foodstuffs under cooking such as, the half-baked, themedium-rare foodstuffs, the instant food and the ready-cookedfoodstuffs, are placed into the stir-frying rotary tank 22 disposed onthe base 2 on the machine stand 1. Then, the required heating period andtemperature are set up by operating the control panel 81 on the controlunit 8 in accordance with the different foodstuffs under cooking. Thedynamic power source 21 is further set with different rotating speed(for example, some sorts of foodstuffs cannot bear over heating whichrequires quick rotation). After being activated, the rotary shaft 211 ofthe dynamic power source 21 drives the stir-frying rotary tank 22 to berevolved and rolled. The high-frequency induction heating unit 3correspondingly provides the heat with appropriate temperature to heatup the foodstuffs under cooking in the stir-frying rotary tank 22, inwhich the heating process is mainly determined in accordance with theset numeric by the control unit 8. For example, as if some sorts offoodstuffs can hardly bear long-term period heating which requiresquickly stir-frying with fully-opened flames to keep and maintain crispand fresh, the electromagnetic valves 302 are set to be fully openedwithin a short time interval to provide an intense and quick full-flamethermal power pulse lasting for few seconds (the other large-flamestage, middle-flame and small-flame discharges electromagnetic valves302 are closed). Alternatively, while some sorts of foodstuffs requireto be stewed by a gentle heating thermal power for a relatively longtime to keep fresh and delicious, a full-flame thermal power is firstprovided until boiled through the fully-opened discharge electromagneticvalve 302. The boiled temperature can be detected by the temperaturetransceiver 82 disposed behind the stir-frying rotary tank 22 and thenbe sent back to the control unit 8. Next, the control unit 8 commands toswitch off the fully-opened discharge electromagnetic valve 302 and thencommands to provide thermal flames by the small-flame dischargeelectromagnetic valve 302 (the other large discharge stage, smalldischarge stage and fully-opened discharge stage electromagnetic valves302 are closed).

During the stir-frying rotary tank 22 is being heated by the strove unit3 for performing the above-mentioned actions, the temperaturetransceiver 82 in the control unit 8 continuously detects thetemperature on the stir-frying rotary tank 22. If the heatingtemperature on the stir-frying rotary tank 22 reaches a predeterminedtemperature and heating period, the stir-frying process is completelyfinished. While the heating process is completed, the control unit 8commands to activate the tilting unit 4, to cause the driving rods 411of both actuators 41 to be moved up to jack up the base 2, whereby thestir-frying rotary tank 22 is thus turned over and the cooked foodstuffsare dumped out. The cooked foodstuffs drop down to the receiving tank 5and the receiving tank 5 is drew out automatically by the automatic pushrod 52 after then (the cooked foodstuffs is ready to eat). The sensor 51used for detecting the movements correspondingly generates and sends asignal back to the control unit 8. Next, the control unit 8 commands toactivate the cleaning unit 6, to cause the water hose 61 to spray outclean water to wash away the leftovers attached and remained on theinner wall of the stir-frying rotary tank 22. A looped guiding plate 63for directing the wasted water carrying the leftovers is disposed underthe water hose 61. Then the air hose 62 blows out massive and compressedair, to air-dry the remaining moisture contents in the tank to ensurethe smells of previous foodstuffs to not remain in the tank.

The wasted water blended with leftovers of the foodstuffs after cleaningis directed to pass through the drying unit 7 on the machine stand 1 toprocess leftovers. The drawer recycling tank 72 is arranged to move bythe sets of slide tracks 71 to receive the wasted water containing withleftovers after cleaning. The wasted water flows out through themultiple apertures 721 opened on the drawer recycling tank 72 and drainsout by passing though the funnel-shape tank 73, in which the dehydratedsolid leftovers are left in the drawer recycling tank 72. While anadequate amount of solid leftovers are accumulated in the tank, thedrawer recycling tank 72 can be pulled out by using the handle 722disposed on the drawer recycling tank 72 and the dried solid leftoversare then dumped into the leftovers collecting tank. The wasted waterprocessing equipment, such as a ditch or a recycling tank, can be usedfor receiving the emission of wasted water.

In addition, during the stir-frying process for the stir-frying rotarytank 22, the cooking and smoking smells might be generated. Thus, asmoke damper can be disposed right above the stir-frying rotary tank 22(shown as where the broken lines marked), to eliminate and to excludesuch peculiar smells.
